Single-segment 100% run of Donkey Kong Country (the game calls it 101%) done in late September 2001. Available in wmv, as well as normal and low quality DivX avi.
Author's comments: Great quality. This was a truly awesome run, where I go straight through the game, winning every level and getting every bonus game without saving, dying or even slowing down. The theoretical limit is probably around 47-48 minutes - yep, the run's that good! Probably my best and most entertaining movie.
